I personally never tried A-Bart. But I have used A-BAB and other Byron White herbs in the past. After reading your post I thought that you might be having some sort of allergic reaction. But you mentioned you stopped the A-Bart several days ago. So it would seem unlikely to be an allergic reaction.
Maybe try a binder like activated charcoal? This might help to bind to the toxin overload. Please remember to take the charcoal 2 to 3 hours away from other meds.
